ROMER Absolute Arm
Absolutely valuable
A first in the world of portable measuring arms: The ROMER Absolute Arm features absolute encoders and is therefore the first measuring arm which does not require referencing before measurement. When the arm is turned on, it's ready to go.
Quality control, inspection, on-machine verification, reverse engineering, virtual assembly or 3D modelling. Wherever these needs arise, you will find the ROMER Absolute Arm. Much more than just a metrology tool, its value lies in its versatility. Portability, stability, light weight and high-performance laser scanners make the ROMER Absolute Arm an all-purpose 3D measurement, analysis and digitising tool that can be used by anyone, anywhere and with minimum training.
Unlike many metrology devices, the ROMER Absolute Arm does not require warm-up time or initialization, thanks to a stable carbon fiber structure and industry leading Absolute encoders. Simply take the measuring arm to the part, switch it on and start measuring.
All models of the ROMER Absolute Arm are available in three levels of accuracy, allowing you to select the right measuring arm for your application requirements and budget. The 73 Series and 75 Series arms offer excellent price/performance ratios for everyday metrology operations, while the 77 Series – the most accurate ROMER Absolute Arm ever produced – is ideal for specialist or high-end measurement applications.
Increasing productivity across all industries.
  • RDS

The ROMER proprietary software RDS features SMART technology, allowing total management of checks in the field as well as temperature and shock monitoring.

  • Laser Scanning

The ROMER Absolute Arm is available with the new fully-certified and integrated RS4 laser scanner designed for faster-than-ever 3D data capture across a range of surfaces and applications.

The fully-certified and integrated RS4 laser scanner is designed to capture 3D point data across a range of surface types. It requires no calibrations, warm-up time or additional cables and controllers. It is totally integrated. With a ultra-wide laser stripe of up to 150 mm, the RS4 can capture 752,000 points per second, reducing the number of passes required to fully scan a part and minimising overall measurement time.

  • Automated & repeatable Probe Recognition

Intelligent Quick Change Probes: Swap touch-probes at any time without the need to recalibrate. The Romer Absolute Arm’s repeatable mount allows to change probes on the fly, according to your measurement needs.

  • Instant Feedback

The ROMER Absolute Arm provides immediate acoustic and haptic feedback to the operator, allowing the Romer Absolute Arm to be used in even the most harsh industrial environments.

  • Absolute Encoders

Referencing and warm-up time was for yesterday – just switch the arm on and measure.

  • Measurement Volume

Size does matter: The ROMER Absolute Arm is available in seven lengths between 1.2 m and 4.5 m.

  • Certification

All ROMER Absolute Arms including scanning systems pass through B89.4.22 certification. Additional certifications according to VDI/VDE 2617-9 are also available. The ROMER Absolute Arm Compact model is available with a choice of ISO 10360-2 or B89.4.22 certification.

  • Zero G

Zero G counterbalance eliminates torque in the base and arm members, more forgiving of the arm being mounted in a vertical position and puts you in control of the arm.

  • SmartLock

If the Romer Absolute Arm is not in use it can be locked safely into its rest position. SmartLock also allows the arm to be fixed in any intermediate position.

  • Feature Packs

Thanks to easily interchangeable Feature Packs, the functionality of the Romer Absolute Arm can always be enhanced. Feature packs are available for wi-fi comunication, wi-fi scanning capability and full battery operation.
